Identify the isoelectronic elements. Ne, Ar, Kr, Xe, He \[ \mathrm{N}^{3-}, \mathrm{S}^{2-}, \mathrm{Br}^{-}, \mathrm{Cs}^{+}, \mathrm{Sr}^{2+} \] \( \mathrm{Cl}^{-}, \mathrm{F}^{-}, \mathrm{Br}^{-}, \mathrm{I}^{-}, \mathrm{At}^{-} \) \[ \mathrm{N}^{3-}, \mathrm{O}^{2-}, \mathrm{F}^{-}, \mathrm{Na}^{+}, \mathrm{Mg}^{2+} \]
